Reliable Airflow Monitoring
The LN 450 GSP-S is an air flow sensor designed to monitor airflow in industrial duct systems, HVAC installations and ventilation applications. It detects air and non-explosive gases within a range of 0.5 to 30 m/s. Its integrated amplifier and two measuring pins support reliable airflow supervision in supply and exhaust air ducts.
Switching Output for Automation
The LN 450 provides a PNP normally open switching output to signal airflow conditions to compatible control systems. This enables integration with industrial automation equipment and ventilation monitoring systems. The 24 V DC supply and M12 connector support straightforward electrical integration.
Compact Design and Industrial Protection
The sensor features a G1 process connection, a PBT housing and sensing components made from Delrin and stainless steel AISI 303. Its IP67 protection rating helps protect the sensor against dust and water ingress under specified conditions. These design features make it suitable for industrial duct installations.
Operating Conditions and Performance
The LN 450 operates with a 24 V DC supply within ±20% and has a maximum current consumption of 60 mA. It supports ambient temperatures from -20°C to 70°C and medium temperatures from -20°C to 80°C. Its switching current is rated up to 400 mA at 20°C, with a typical reaction time of 2 to 30 seconds.
